Niña de la Tierra: Children of the Earth

No it's not the title of a horror film, Children of the Earth is actually one of the many common names for Stenopelmatus fuscus. Other names lovingly given to this insect are Jerusalem Cricket, Potato Bug, Skull Insect, and my personal favorite, Devil's Baby!

Earlier this week Sam Easterson found one in his front yard and captured this picture and footage.

Are you Looking at Me?






These crickets are very common in Los Angeles. Consequently, my colleague Brian Brown, the Museum's Curator of Entomology, and I get calls about them all the time. I most often get calls after heavy rains, when these crickets come up from the depths of their soily abodes. They are stellar diggers (Check out their fossorial front legs, modified for digging) and live most of the...

North Campus Insect Survey

Survey Fun
 
 
As mentioned in an earlier post New Fly for North Campus, we've been trapping insects on the North Campus for a while now. This week however, is a milestone for NHM as we held our first quarterly insect survey. Our aim was to go after the insects that our Malaise trap wasn't sampling, like large flying insects such as crane flies and bumble bees and ground dwelling insects like earwigs and beetles.  Since this was our first time and the site is still an active construction zone, we limited participation to NHM staff and partners. As the specimens get prepared and sorted, I'll keep you all up to date on the species we identify.

New Fly for North Campus

Insect Trapping

To better understand the insect diversity of the North Campus, we've started surveying the insect fauna on the construction site. A few months ago, Dr. Brian Brown, the Museum's Curator of Entomology, set up a Malaise trap. This type of trap is commonly used by entomologists to capture small flying insects, and so far we've collected hundreds! One of the coolest (at least in Brian's opinion, and now mine too) is the Boatman Fly.

(yes Entomologists take their work home with them too!)

The Boatman Fly, Pogonortalis doclea, is a small (1/4 inch) fly originally from Australia. It was first recorded in California in 1963, and to date has not been recorded in any other state.  These flies are quite...
